WEATHER STRIP.

Application filed September '7, 1926. Serial No. 134,017.

This invention aims to provide a novel means whereby air will be prevented from flowing between a window sash and a window "frame, the device being so constructed that it will be well adapted to withstand severe and long continued use.

It is within the province. o1 the disclosure to improve generally and to enhance the utility of devices of that type to which the invention ap pertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in. vention herein disclosed, may be made within the scope of what is claimed, without depart ing from the spirit of the invention.

In the drawings Figure 1. shows in horizontal section, a window -trame and a pair of window sashes equipped with the device forming the subject matter of this application;

Figure 2 is a perspective view showing one of the weather strips; and

Figure 3 is a perspective view showing the other of the weather strips.

The numeral 1 marks the vertical stile of a window "frame, the window frame including a face plate 2, a guide piece st, and a parting strip 3 between the face plate 2 and the guide piece l. The construction above alluded to may be described briefly as a stile provided with outstanding guide members. The sash 5 is slidable between the face plate 2 and the parting strip 3. A sash. G is slidablc between the parting strip 3 and the guide piece 4;. There is a recess 7 in that corner of the sash (S which is adjacent to the parting strip-3. There is a similar rece's in that edge of the sash 5 which is adjacent to the face plate 2. The sashes 5 and 6 are provided with shallow superficial seats 8 which con'nnunicate with the recesses 7.

The numeral 9 marks a resilient metal strip having a wide wing 10 provided with openings 11 adapted to receive securing elements 12 whereby the strip 9 may be secured to the stile 1 along one edge of the sash. The wing 10 has a hook-shaped bead 1 1 including a bend 15.

A metal strip 16, made of resilient metal. is provided, the strip including a flange 17 having openings 18 adapted to receive sec-uring elements 19 whereby the strip 16 is secured to the sash 6, the flange 17 being located in the seat 8. The flange 17 is provided with a sign'ioidal portion 20 located in the recess 7, the said sigmoidal portion 20 embodying an inner trouglrshaped part 21 and an outer trough-shaped part 22, the troughshaped part 22 being provided with a lip ZS.

The hoop-shaped bead 14: receives the part ot' the sigmoidal portion 20 closely but slidably, and the free edge of the bead 14 is received closely but slidably in the part 21. The wing 10, owing to its resiliency, bears ciosely but slidably on the lip 23. The bond at 15 bears slidably against the parting strip 3. The construction above described is carried out in connection with the sash 5, aside from the tact that the bend at 15 bears against the face plate 2.

it will withstand wear and be extremely effective to keep out the weather and turn drafts of air.

lVhat is claimed is:-

In, a device otthe class described, a weather strip e nbodying a. wing having a hookshaped bead, and a weather strip embodying a flange havin a sign'ioidal portion including an inner trouglrshaped part, and an outer trouglnshaped part having a lip, the outer trough-shaped part litting closely and sli lably in the hooleshaped bead, and the free edge of the hook-shaped bead fitting closely and siidable in the inner trough- .shaped. part, the lip being disposed at right angles to the flange and being in slidable contact with the wing, the inter-fitting portions 03": the sigmoidal portion and the -hoole shaped bead being parallel, whereby they may be separated transversely without distorting either of them. I

in testimony that I clain'i the "foregoing as my own, I have hereto affixed my signature.

FRANK E. CALDl VELL- The construction of the device is such that
